1 Mln of records... how show them?

[Christian OLIVIERI]

Hi guys, I have a problem driving me crazy. I have to show (JSON) 1 mln of records using web services. Server procedure is:

function getCiaos()
{
        $mysqli = new mysqli("localhost", "yyy", "xxx", "master");
        $uresult = $mysqli->query("SELECT id, data FROM ciao", MYSQLI_USE_RESULT);
        $arr = array();
        if($uresult) {
                while($row = $uresult->fetch_array(MYSQLI_ASSOC)) {
                        $arr[$row['id']] = $row;
                }
        }
        $uresult->close();
        $mysqli->close();
        return $arr;
  }

Client side is:

$client=new SoapClient('http://www.example.com/webservice/nu2.php?wsdl', array('trace' => 1));
        $res = $client->getCiaos();
var_dump($res);

Always php client show Internal error and Apache log show me:
PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted

Do you know a way to show these large datas without increase php_ini setting?

Thank a lot!
